Key Features & Benefits:Activates Deep Core Muscles: The 25cm size is small enough to grip between your thighs or press against a wall, forcing your abs and inner thighs to engage throughout every rep. It's like having a personal trainer cueing "squeeze!" without paying for one.Anti Burst Construction Handles Real Use: Built with thickened PVC that compresses under pressure instead of popping. You can squeeze it, sit on it, or press your full body weight against it during exercises without worrying about sudden deflation mid workout.Non Slip Texture Stays Put: The matte, slightly textured surface grips your skin and workout clothes so the ball doesn't squirt out from between your knees during leg lifts or roll away during back extensions.
